论中国铅锌矿床的主岩+成因综合分类OA北大核心CSTPCD

Objectives:Classification of lead-zinc deposits is one of the mainest research subjects on lead-zinc ore geology. Methods:During the research and compilation of Annals of Geology of Mineral Resources in China——Lead and Zinc Mineral Resources,the writer carried out a more detailed survey,analysis and arrangement of the references related to classification of lead—zinc deposits in China and in the world,and suggested the host rock—genesis classification of lead—zinc deposits in China on the basis of studies on many important lead—zinc deposits in China and other countries. Results:The Chinese lead—zinc deposits have been classified into 11 types.The 11 types include sediment-hosted sedimentary—exhalative type,carbonate-hosted(epigenetic)type,sandstone lead and sandstone—conglomrate type,volcanic-hosted massive sulfide type,intrusion-related type,continental volcanic rock type,non-magmatic meso-epithermal type,non-sulfide type,placer type,composite type and superimposed type. Conclusions:The comprehensive(host rock+genesis)classification of lead—zinc deposits in China can cover the types,subtypes,styles and representative deposits of the whole country.Composite type and superimposed type are the characteristics of lead—zinc deposits in China,and the prospecting prospect of them is good,so the exploration and development and research of them should be strengthened.
